Description

Display module with elastic fixed design

The present invention relates to a display module; in particular, the present invention relates to a display module having an elastic fixed design.

The display device is mainly composed of a display panel, a backlight module, a plastic frame and an outer frame. The conventional display device is configured to set the display panel on the plastic frame, and limit the moving range of the display panel in the plane direction of the plastic frame by the plastic frame to fix the display panel. However, the reserved space between the end face of the display panel and the plastic frame is limited. When the ambient temperature changes or the internal temperature changes due to the operation of the display device, the end face of the display panel may come into contact with the plastic frame, and further cause the plastic frame to be laterally Squeeze the display panel. At this time, the light generated by the backlight module may have uneven brightness and light leakage at the extrusion of the display panel.

In particular, the display device with narrow frame design can reduce the space occupied by the plastic frame and the outer frame in the edge region of the display device by using the narrow frame technology, so that the range of the display screen is increased, but the display device of the narrow frame design is on the end surface of the display panel. The spacing between the frame and the frame is smaller, so that the aforementioned problem of light leakage is more likely to occur, resulting in a visual effect of a plurality of bright and uneven edges on the edge of the corresponding display device on the screen. This display is still not ideal. Therefore, the structure of the existing display device still needs to be improved.

An object of the present invention is to provide a display module that can reduce light leakage caused by compression of a display frame and maintain a certain assembly reliability.

Another object of the present invention is to provide a display module that can reduce the stress that the display panel is subjected to due to thermal expansion and contraction.

The display module includes a carrier frame and a display panel. The carrying frame has a side wall and a flap. The flap projects from the outer side of the load bearing top surface of the side wall away from the load bearing top surface. The sidewalls respectively form slits of the undercut sidewalls on both sides of the baffle, and the sidewalls form weakened holes under the baffle. The display panel is disposed on the carrying frame, and the bottom surface of the display panel is supported by the carrying top surface, and the blocking piece is opposite to the end surface of the display panel. By the design that the two sides of the blocking piece are separated from the side wall portion, when the display panel is pressed by the carrying frame, the blocking piece has elasticity and can move outward, which can reduce the lateral pressing force of the carrying frame to the display module.

The invention provides a display module, wherein the carrier frame has a design of a flap. The flap can be moved under pressure to reduce the stress generated when the carrier frame is pressed against the display panel. In a preferred embodiment, the display module is preferably used in a flat display device such as a liquid crystal display device or the like.

1 is an exploded view of an embodiment of a display module 100 of the present invention. As shown in FIG. 1 , the display module 100 includes a carrier frame 110 and a display panel 130 . The display panel 130 is disposed on the carrying frame 110, and the polarizing plate 150 is optionally disposed on the upper and lower sides of the display panel 130. The carrying frame 110 has a sidewall 112 and a blocking piece 114 , and the blocking piece 114 is opposite to the end surface 132 of the display panel 130 . Referring to FIG. 1 and FIG. 2A , as shown in FIG. 1 , the bearing frame 110 is formed around an accommodating space 111 for accommodating the display panel 130 . In a preferred embodiment, a backlight module (not shown) may be disposed in the accommodating space 111 to provide backlight. The sidewall 112 has a load bearing top surface 116 formed on the inside of the flap 114. As shown in the cross-sectional view of FIG. 2A, the bottom surface 134 of the display panel 130 is supported by the load bearing top surface 116. The flap 114 preferably projects from the outer side of the load bearing top surface 116 of the side wall 112 in a direction away from the load bearing top surface 116. That is, in the cross-section shown in FIG. 2A, the blocking piece 114 protrudes longitudinally from the carrying top surface 116 such that the top surface 117 of the blocking piece 114 has a height difference from the carrying top surface 116, thereby limiting the display panel 130 to a horizontal level. The movement of the direction.

As shown in FIG. 2A, the flap 114 is opposite the end surface 132 of the display panel 130. In this embodiment, the height of the side walls 112 on both sides of the blocking piece 114 is lower than the height of the blocking piece 114, as shown in the figure. As shown in FIG. 2B, the display panel 130 is located on the top surface of the carrier (indicated by a dotted line on the shutter 114, which is a horizontal position for carrying the top surface). The end face portion of the display panel 130 is shielded by the blocking piece 114, and the remaining portion is exposed outside the side wall 112 and the blocking piece 114. The movement of the display panel 130 in the horizontal direction is restricted by the shutter 114, and the contact range between the end surface of the display panel 130 and the carrier frame 110 is reduced, thereby avoiding light leakage.

As shown in FIG. 1 , the side walls 112 respectively form slits 118 of the undercut sidewalls 112 on both sides of the blocking piece 114 . In this embodiment, since the blocking piece 114 protrudes from the carrying top surface 116, and the slit 118 is cut downward into the side wall 112 by the carrying top surface 116, the slit 118 is substantially below the blocking piece 114, but is not limited thereto. In one embodiment, the side wall 112 and the blocking piece 114 are preferably made of a single material, and the blocking piece 114 is formed by the undercut sidewall 112. However, in other embodiments, the side walls and the flaps may be of different materials. For example, a position on the side wall where the baffle is to be provided (for example, a circle in the drawing) is first formed into a recessed portion, and then the baffle is placed in the recessed portion so that the baffle protrudes above the top surface of the load bearing, and the block is blocked. The sheet has a gap with the side walls on both sides. The slit is formed by the undercut, and the left and right sides of the flap are separated from the side walls to be elastic. 2C is a cross-sectional view showing the module pusher flap. As shown in FIG. 2C, when the display panel 130 is pressed by the carrier frame 110, the blocking piece 114 has elasticity and moves outward to reduce the pressing force on the display panel 130.

3 is a cross-sectional view of a different embodiment of a carrier frame. As shown in FIG. 3, the outer surface 113 of the side wall 112 is retracted inwardly relative to the flap 114, forming a recessed space below the flap 114. The concave space can be used in combination with the outer frame to reduce the space occupied by the carrying frame 100 and the outer frame. In this way, in addition to providing an effect of improving light leakage, the need for a narrow bezel can be taken into consideration.

For the setting of the shutter, please refer to the description of FIG. 4 to FIG. 6A. 4 is a top view of an embodiment of a carrier frame 110. As shown in FIG. 4, a flap 114 is formed at a position close to the four corners of the carrier frame 110. Therefore, when the display panel is pressed by the carrying frame 110, the position of the display panel at the corresponding blocking piece 114 can reduce the lateral pressing force of the carrying frame 110 on the display module, and improve the light leakage. situation. In addition, the number of flaps 114 and the position formed can be adjusted as needed. For example, please refer to the top view of different embodiments of the carrying frame of FIG. 5 and FIG. 6A. As shown in FIG. 5, a plurality of blocking pieces 114 are formed along the short sides (110a, 110b) on both sides of the carrying frame 110, but are not limited thereto, and may be added to the long sides (110c, 110d) as needed. Thereby, the lateral pressing force of the bearing frame on the display module can be reduced and the light leakage can be improved.

As shown in FIG. 6A, a plurality of blocking pieces 114 are formed along the short sides (110a, 110b) and one long side 110c of the two sides of the carrying frame 110, and the blocking piece 114 is not disposed along the other long side 110d of the carrying frame 110. In this embodiment, the corresponding position of the long side 110d of the flap 114 is not provided with a cushioning material to reduce the situation of pressure leakage. As shown in the cross-sectional view of FIG. 6B, the bottom surface 134 of the display panel 130 is supported by the load bearing top surface 116 of the carrier frame 110. The outer frame 170 is covered on the display panel 130, and the outer frame 170 is provided with a cushioning material 200. The cushioning material 200 is filled between the outer frame 170 and the end surface 132 of the display panel 130. In other words, the buffer material 200 corresponds to one end surface of the display panel 130 (on the same side as the long side 110d), and the plurality of shutters 114 are respectively distributed corresponding to the other end surfaces of the display panel 130. With this design, when a display panel of a larger size is used, since the position of the bottom of the display panel after suspension (for example, corresponding to the long side 110d described above) is a load-bearing edge, it may be easy to generate a light leakage. The cushioning material filled between the end surface of the bottom edge and the outer frame can further reduce the pressure on the display panel by the better elasticity of the cushioning material to improve the light leakage, and the other end faces of the display panel can still be fixed by the blocking piece.

For the cooperation between the carrier frame and the outer frame, please refer to FIG. 7A and FIG. 7B. As shown in FIG. 7A , the display module 100 includes an outer frame 170 covering the display panel 130 and surrounding the outer side of the sidewall 112 . As shown in FIG. 7B (only the carrier frame and the outer frame are shown), a hole 172 is formed in the outer frame 170 at a position corresponding to the blocking piece 114 to allow the blocking piece 114 to move toward the hole 172. Thereby, when the display panel 130 is pressed by the carrying frame 110, as shown in FIG. 7C, the blocking piece 114 has elasticity and can move toward the outer frame 170, and the hole 172 in the outer frame 170 reserves the blocking piece 114. Moving space, The flap 114 is prevented from being restricted by the outer frame 170 and cannot be extrapolated to provide an effect of light leakage improvement.

In addition to the foregoing design that only restricts the movement of the display panel by the shutter, in other embodiments, the carrier frame can also be adjusted as needed to limit the movement of the display panel together with the side walls. Please refer to FIG. 8A to FIG. 8C. As shown in FIG. 8A, the carrying frame 110 has a side wall 112 and a blocking piece 114. The sidewall 112 has a carrying top surface 116 formed on the inside of the carrier frame 110. The sidewalls 112 form slits 118 of the undercut sidewalls 112 on opposite sides of the baffle 114, respectively. The blocking piece 114 extends from the outer side of the carrying top surface 116 of the side wall 112 away from the carrying top surface 116. As shown in FIG. 8B, the display panel 130 is disposed on the carrying frame 110. The bottom surface 134 of the display panel 130 is supported by the load bearing top surface 116. The flap 114 is opposite the end surface 132 of the display panel 130.

Referring to FIGS. 8A and 8C, as shown in FIG. 8A, a weakened hole 120 is formed below the baffle 114 below the load bearing top surface 116. The weakened hole 120 is preferably formed as an elongated through hole perpendicular to the slit 118. As shown in the side view of FIG. 8C, a slit 118 is formed on both sides of the flap 114 and the side wall 112, and the depth h of the slit 118 under the sidewall 112 exceeds the top edge 120a of the weakened hole 120. In other words, the slit 118 extends downward to a horizontal position lower than the top edge 120a of the weakening hole 120, so that the periphery of the blocking piece 114 is formed by the left and right sides of the weakening hole 120 and the side wall 112. By this design, the left and right sides of the blocking piece 114 are separated from the side wall 112, and the connection area under the blocking piece 114 with the side wall 112 is reduced, so that the blocking piece 114 has elasticity. In the preferred embodiment, the depth h of the undercut sidewall 112 of the slit 118 exceeds the bottom edge 120b of the weakened hole 120, and the sidewalls 112 on both sides of the weakened hole 120 are respectively formed into pillars to connect the upper and lower portions of the weakened hole 120. Further, the connection area under the blocking piece 114 and the side wall 112 is further reduced, so that the blocking piece 114 is more elastic.

On the other hand, the width w _{1 of the} flap 114 is slightly larger than the width w _{2 of the} weakening hole 120. Specifically, the width ratio (w ₁ :w ₂ ) of the blocking piece 114 and the weakening hole 120 in the direction of the parallel bearing top surface is preferably between 7:3 and 7:6. In a more preferred embodiment, the width ratio of the blocking piece 114 and the weakening hole 120 in the direction of the parallel bearing top surface is substantially 7:5, thereby not only making the blocking piece 114 elastic, but also maintaining a certain strength. Limiting the movement of the display panel 130 provides a better fixation effect.

In addition, the height of the flap 114 and the side wall 112 can be adjusted in terms of the fixing effect. As shown in FIG. 8A, on the carrying frame 100, the height of the side walls 112 on both sides of the blocking piece 114 coincides with the height of the blocking piece 114. As shown in the embodiment of FIG. 8C, the side walls 112 of the two sides of the blocking piece 114 are also opposite to the end surface 132 of the display panel 130, that is, the end surface 132 of the display panel 130 is shielded by the blocking piece 114 and the side wall 112. In this embodiment, the position of the blocking piece 114 is preferably slightly retracted from the side walls 112 of the opposite sides (refer to FIG. 8A, the blocking piece 114 is retracted toward the accommodating space 111), so that when the display panel 130 is pressed by the carrying frame 110, the first The contact piece 114 with elastic design is contacted to reduce the pressing force. With this design, the shutter 114 and the side wall 112 together limit the movement of the display panel 130 to enhance the fixing effect while maintaining the effect of solving the pressure leakage.

Figure 9 is a side elevational view of an embodiment with sidewalls having different slits. As shown in FIG. 9 , the difference from the previous embodiment is that the slit 118 formed by the side wall 112 under the two sides of the blocking piece 114 is a downwardly cut notch, and the gap increases toward the weakening hole 120 as the depth of the lower cutting increases. The flap 114 has a form of upper width and lower width. In other words, the width w _{1 of the} flap 114 gradually narrows as the depth of the undercut of the slit 118 increases. With this design, the portion above the blocking piece 114 can cover more end surface areas of the display panel 130, that is, the area where the end surface of the display panel 130 is subjected to pressure leakage is reduced; the portion below the blocking piece 114 can be adjusted by the slit 118. The distance between the weakened hole 120 and the weakened hole 120 changes the connection area between the lower side of the blocking piece 114 and the side wall 112, so that the blocking piece 114 elastically fixes the display panel 130.

Further, by using the display module of the design in which the end surface of the display panel is exposed at a portion other than the shutter as shown in FIG. 1 described above, the weakening hole can be further provided to adjust the elasticity of the shutter. Please refer to FIG. 10A to FIG. 10C for another embodiment. As shown in FIG. 10A, the carrier frame 110 has a side wall 112 and a flap 114. The sidewall 112 has a carrying top surface 116 formed on the inside of the carrier frame 110. Side wall 112 A slit 118 of the undercut sidewall 112 is formed on both sides of the shutter 114, respectively. The flap 114 extends from the outer side of the load bearing top surface 116 of the side wall 112 away from the load bearing top surface 116, and the height of the side wall 112 on both sides of the flap 114 is lower than the height of the flap 114. As shown in FIGS. 10A and 10B, the sidewall 112 forms a weakened hole 120 under the baffle 114.

Referring to the side view of FIG. 10B, the weakened hole 120 is located below the flap 114. The bottom surface 134 of the display panel 130 is supported by the load bearing top surface 116. The flap 114 is opposite the end surface 132 of the display panel 130. As shown in FIG. 10C, the display panel 130 is located on the top surface of the carrier (indicated by a dotted line on the shutter 114, which is a horizontal position carrying the top surface). The end face portion of the display panel 130 is shielded by the blocking piece 114, and the remaining portion is exposed outside the side wall 112 and the blocking piece 114.

Please refer to FIG. 10A and FIG. 10C. As shown in FIG. 10A, slits 118 are sandwiched between the sides of the flap 114 and the side walls 112. As shown in the side view of FIG. 10C, the depth h of the undercut sidewall 112 of the slit 118 exceeds the top edge 120a of the weakened hole 120. In other words, the slit 118 extends downwardly to a level below the top edge 120a of the weakened hole 120. The periphery of the blocking piece 114 is formed only by the left and right sides of the weakening hole 120 and the side wall 112. By this design, the left and right sides of the blocking piece 114 are separated from the side wall 112, and the connection area under the blocking piece 114 with the side wall 112 is reduced, so that the blocking piece 114 has elasticity. In this way, the blocking piece 114 can be used to limit the movement of the display panel 130 in the horizontal direction, and the elasticity of the blocking piece 114 is increased by the weakening hole 120 to reduce the lateral pressing force of the bearing frame 110 on the display panel 130, and the improvement is improved. Light leakage.

In summary, the display module of the present invention can fix the display panel by the baffle, and the elastic baffle can reduce the light leakage caused by the pressing of the display frame by the display panel. The design of separating the two sides of the blocking piece from the side wall portion can reduce the lateral pressing force of the bearing frame on the display module, thereby reducing the uneven brightness of the display device due to pressure leakage, and improving the display effect.

The present invention has been described by the above-described related embodiments, but the above embodiments are merely examples for implementing the present invention.
